I've got some new hard drives, that I want to use with linux software
raid as raid-1 arrays. System is Debain 6.0.0 (squeeze). Grub is
1.98+20100804-14. I'm booting off Debian 6.0.0 live CD, partitioned the
new disks, created the arrays, created filesystem on them, mounted them,
and copied from old drives onto new arrays.
But I can't get them to boot.
I've mounted /dev/md0 on /newdisk, then run:
grub-install --root-directory=/newdisk --recheck /dev/sda
This installs grub on the disk OK. But it doesn't create a working
/boot/grub/grub.cfg. This seems to be an oversight. update-grub doesn't
work in this situation, even if 'chroot /newdisk'.
So when booting, I end up with grub command prompt>
I've tried then booting manually with:
set prefix=(md/0)/boot/grub
set root=(md/0)
insmod linux
linux /boot/vmlinuz-2.6.38 root=/dev/md0 ro
initrd /boot/initrd.img-2.6.38
boot
This starts to boot, but then drops to busybox prompt with message that
it can't mount the arrays (/dev/md0, being the root partition). But I've
got raid-1 support compiled into the kernel (rather than as module). So
I don't know what the problem is.
Much obliged if anyone can suggest something.
regards, Tim
